Le Chatelier Water Bath

A Le Chatelier Water Bath is used to determine the volume changes that occur in certain materials, such as cement, by measuring the expansion or contraction of a cement sample when subjected to different temperatures or pressures. The apparatus consists of a water-filled container with a graduated glass vessel immersed in it. The glass vessel has a small opening at the top for adding materials, and it is designed to measure changes in volume accurately. This information is essential for assessing the quality and performance of the cement under various conditions. Le Chatelier Water Bath comes with Fully Stainless Steel inside and exterior casing. Able to hold up to 12 Le Chatelier moulds in the removable mould rack. Both temperatures can reach boiling point in approximately 30 minutes.

Features of Le Chatelier Water Bath

  • Fully Stainless Steel Construction: Both the interior and exterior casing of the water bath are made of stainless steel, providing durability and resistance to corrosion.
  • Capacity: It is capable of holding up to 12 Le Chatelier molds simultaneously, which are housed in a removable mold rack. This feature enables batch testing and efficient utilization of laboratory space.
  • Temperature Control: The water bath is equipped with temperature control capabilities, allowing it to reach and maintain specific temperatures required for the testing process. The temperature can reach boiling point in approximately 30 minutes, ensuring rapid heating for efficient testing procedures.
  • Graduated Glass Vessel: The graduated glass vessel immersed in the water bath allows for accurate measurement of volume changes in the material being tested. It features a small opening at the top for adding materials and is designed to provide precise volume readings.

Standard: BS 6463, EN 196-3, pr EN ISO 9597

  • BS 6463 

Specification for Reinforced Plastics Pipes, Fittings, and Joints for Process Plants. It provides specifications for reinforced plastic pipes, fittings, and joints intended for use in process plants. This standard covers aspects such as materials, dimensions, testing, and installation procedures for reinforced plastic piping systems used in industrial applications.

  • EN 196-3

Methods of Testing Cement - Part 3: Determination of Setting Times and Soundness. Determining the setting times and soundness of cement. Setting time refers to the time taken by cement to harden after mixing with water, while soundness refers to the ability of the cement to retain its volume after setting without excessive expansion or shrinkage.

  • pr EN ISO 9597

This refers to a draft European Standard (prEN) based on an International Organization for Standardization (ISO) standard. This standard specifies test conditions and methods for assessing the geometric accuracy of machining centers with vertical spindles or universal heads having a vertical primary rotary axis (Z-axis). It provides guidelines for conducting geometric tests to evaluate the performance and accuracy of such machining centers.

Test Procedure of Le Chatelier Water Bath

  1. Preparation of Equipment: Ensure that the Le Chatelier Water Bath is clean and free from any residues. Fill the water bath with distilled water up to the required level. Set the water bath to the desired temperature, usually around the boiling point of water.
  2. Preparation of Cement Sample: Prepare a cement sample by accurately weighing it according to the test specifications. Place the cement sample in a Le Chatelier mold, ensuring it fills the mold.
  3. Initial Measurement: Measure the initial length of the cement sample using a suitable measuring device, such as a caliper, and record the value.
  4. Immersing the Sample: Carefully place the Le Chatelier mold containing the cement sample into the water bath, ensuring it is fully immersed in water.
  5. Boiling and Timing: Allow the water bath to reach boiling point and maintain it at that temperature. Start the timer and allow the cement sample to boil for a specified period, typically 3 hours.
  6. Cooling and Final Measurement: After the boiling period, remove the Le Chatelier mold from the water bath and allow it to cool to room temperature. Once cooled, measure the length of the cement sample again and record the final value.
  7. Calculations: Calculate the difference between the initial and final lengths of the cement sample. This difference represents the expansion or contraction of the sample due to the applied temperature. Express the volume change as a percentage of the initial length or volume of the cement sample.
  8. Analysis and Reporting: Analyze the results to assess the soundness and stability of the cement sample. Report the findings, including the volume change and any relevant observations, in accordance with testing standards or project requirements.
